5. Solve for x.<br> I keep getting different answers ranging from 35 to 56
Anna35 [415]

Answer: 21

<u>Step-by-step explanation:</u>

x is a tangent line, 56-7 is a secant line.  The length is equal to the outside segment times the entire segment. <em>Notice that the length of the outside of the segment is equal to the entire segment for the tangent line.</em>

x^2=7(56+7)\\\\x^2=7(63)\\\\x=\sqrt{7(63)}\\\\x=\sqrt{7(7\cdot 9)}\\\\x=7\cdot 3\\\\\large\boxed{x=21}

At what value of x do the graphs of the equation below intersect ?<br> 2x-y=6<br> 5x+10y=-10
Y_Kistochka [10]

Answer:

x = 2

Step-by-step explanation:

Solve the two equations simultaneously....whereby you substitute y = 2x - 6 from the above equation into the second equation...

where...; 5x + 10(2x - 6) = -10

5x + 20x - 60 = -10...then move the variables with x to one side...

5x + 20x = -10 + 60

25x = 50

;Therefore...the value of x at intersection point = 2

Use compass directions to describe the Direction of a vector. The diagram is not drawn to scale
vekshin1
Using compass directions we simply describe the direction using the angle relative to N, S, E & W.

So in this case, the vector is travelling south west at an angle "41 degrees South of West."
